TANDEM ATTACHMENT FOR GARMENT-PRESSESE To all whom'z't may co ncemfl Beit known that T, VILLIAM E. ANnRiiE,

'a citizen of the United States, residing at be used in conjunction orassociated relation with each other so that a single operator canreadily manipulate two presses.

The objects of the invention are to improve the mechanism or meansconnecting the two presses; to provide means for read- 1 ilydisconnecting the presses so that they can be operated individually; toprovide automatic means for releasing the pressure treadle; and to alsoprovide mechanism of this character in which the presses can readily beplaced and operated at varying angles to each other.

Further objects of the invention are in part obvious and in part willappear more in detail hereinafter.

In the drawings, Figure 1 represents a front elevation illustrating twopresses interconnected according to the present invention, one pressbeing 'open and the other closed; Fig. 2 is a horizontal section on theline 22, Fig. 1, the treadle locking and release mechanism being omittedfor clearness of illustration; Fig. 3 is a detail view, partly insection, illustrating the connectmg rod and universal joints; Fig. 4; isa -ed operation.

Specification of Letters Patent.

Application filed November 8, 1919. Serial No. 336,574.

Serial No. 336,573. The press comprises a suitable frame 1 carrying astationary garment support 2 with which coiiperates an upper pressingmember or head 3 carried by a swinging lever which comprises two membersone of which, marked 4, is pivoted at 5 to the frame and is pivotallyconnected at 6 to a second member 7- having a screw connection 8 withmember t for relativeadjustment between said members. The head iselevated by a tension spring or springs V 9 and is moved downwardly intopressing relation with the garment support by depressing the foottreadle 1O pivoted at 11 to the frame and connected by a link 12 to onearm 13 of a lever pivoted at 14 in the frame, the other arm 15 of saidlever being connected by a link 16 to the lower end of member 7. Anyother operating mechanism for producing relative motion between thepressing members would be satisfactory for use with the presentinvention.

As is usual in such, presses suitable means is provided for locking thepressing members in pressing relation, said mechanism operatingmechanism for said members, such as the pressure treadle. The mechanismshown for this purpose in the drawings is of the-.same constructionillustrated in my copending application for release treadle for garment.presses filed of .even date here-- with, Serial No. 336,573. Brieflydescribed said mechanism comprisesa locking lever 17 pivoted at 18 to abracket 19 carried by the frame, the'upper arm 20 of said lever beingnormally pressed outwardly by a compression spring 21. The lower arm ofsaid lever is provided with a'cam surface 22. a longitudinally extendingsurface 23, and a locking toe 24, and in front of said cam surface hasan extension provided with an abutment 25. Pivoted at 26 tosaid. leverthe release treadle 27 provided witha releasing lug crates with theabutment 25and-a second 28, a stop lug 29 -which coopabutment 30 on thelocking toe, and which release treadle is also provided with an upwardlyextending arm 31 provided with a finger 32. On a stationary bracket orsupport 33 is pivoted at 34 a free motion treadle a 35 normally held inits upper position by a tension spring 36 and from which free motiontreadle hangs a swinging wedge coiiperating with a part of th 80 Imember 37. 50 indicates a i'oller on the locking lever and 39 a rollercarried by a pin ing back into the press and connected by a link 41 withan arm 42 on a shaft 43' journaled in the machine frame. The shafts 43of the two machines are connected by any suitable mechanism so as torotate in unison with eachother. As illustrated, these shafts areconnected by a rod 44 of non-circular cross section, such assqua're,.the opposite ends of which enter non-circular openings in theuniversal joint members 45 provided with sleeves 46 to receive the endsof. the shaft members 43 and which are made to rotate with the shafts,such as by the provision of keys 47 and clamping screws 48.for securingthe sleeves 46 to the shafts 43.

. Rod 44 is of such len th that when the parts ment thereto.

are assembled, as in ig. 3, said rod can be pushed endwise into one ofthe universal joint sleeves 45 so as to free its opposite end from theother universal joint to thereb enable the two presses to be disconnecteand said rod is locked and secured in place when the presses areconnected by a set screw 49.

In the drawings, press A is shown open and press B closed. During theclosing movement of press B its roller 39 moved along the cam surface 22and vertical surface 33 until said roller passed the locking toe 24,which thereupon moved rearwardly into locking position above saidroller, as shown in Fig. .1. While press B is closed and the garmenttherein is receiving ironing pressure the operator removes the work fromthe open press A and applies another gar- The operator then closes pressA byde'pressing its ressure treadle 10. The'roller 39 of press thereuponactuates its locking lever 17 so as to swing its lower end outwardly toallow said roller to reach locking position. The swinging motion oflever 17 of press A produces similar motion of the locking lever ofpress B, so that the roller 39 of ressB is released and said ,pressopens. onsequently when the two presses are connected-closing movement\of one-press releases and permits opening movement of the other press.

If it is desired to operate the presses with free motion, or, in otherWords, to raise and lower the pressing head without locking the same inits depressed position, the free mo tion treadle of either or bothpresses is deing the rod 44, produce similar adjustment of both lockinglevers. With this arrangement each press is free of locking relationwith the other and both presses can be operated individually but withoutlocking effect and without any necessity of .direct operation of therelease treadles.

If itis desired to operate the presses individually with looking effectand without associated relation the set screws 48 and 49 are loosened,.the rod 44 is removed and the universal joints taken" off. Eachpress is then wholly independent of the other? Depression of the releasetreadle 27 causes its arm 31 to rise and the finger 32, which liesunderneath the freemotion treadle elevates the same soas to withdraw thewedge. 37 from behind the. roller 50. This restores the locking lever tooperative condition.

words, looking at Fig. 2, where C indicates I the front or operatingstation at each of the two presses, each ress can be turned from thefull line position around a vertical axis 51 through the universal jointto any amount toward the dotted line position.

With this range of adjustment and the additional range secured v by 1lengthening or shortening the rod 44 almost any desired relation betweenthe presses can be secured, as will be obvious.

The universal joint connection between the two machines also doesawaywith any necessity for accurate setting of ,the two 'machinesrelative to each other, as the two machines can be slightly askew from asymmetrical position' and can be mounted at different levels withinreasonable limits.
